In addition to re-signing linebacker O’Brien Schofield, the Seattle Seahawks on Friday announced that they have signed cornerback A.J. Jefferson and have declined guard James Carpenter’s option for the 2015 season.

Meanwhile, wide receiver Doug Baldwin will remain with the Seahawks in 2014, though he has not yet officially signed. He has an offer on the table for one year at $2.187 million from Seattle, but it remains to be seen whether he will sign a long-term deal.

A restricted free agent this offseason, Baldwin hadn’t gotten an offer from another team by Friday’s deadline. Seattle had placed a second-round tender on the 25-year-old, meaning another team would have surrendered a second-round draft pick to sign him.

Carpenter, 25, is entering the fourth year of his rookie contract after being drafted 25th-overall in the first round of the 2011 NFL Draft. After missing seven games his rookie year and nine games in 2012 with knee injuries, Carpenter was healthy enough to play in every game last season — including 10 starts — but still did not show first-round talent on the football field.

However, Carpenter did provide much-needed help on the offensive line, which was thin for much of the season due to injuries. Carpenter struggled in run blocking and performed decently when pass blocking, but apparently hasn’t shown Seattle’s coaching staff he deserves an early commitment for 2015.

The offensive line is considered a key need for the Seahawks heading into next week’s NFL Draft.

Meanwhile, cornerback Jefferson joins Seattle after four years in the pros, mainly as a backup. An undrafted free agent in 2010 out of Fresno State, the 26-year-old has 14 starts in 43 NFL games with the Cardinals and Vikings.

Traded from Arizona to Minnesota in 2012, Jefferson was released by the Vikings in November 2013. He has two-career interceptions and 107 total tackles over his four seasons in the NFL.
